ge tests to be carried out on instruments and systems

using pulse bursts similar to those that occur in practice when electrical equipment is switched on or

off, or when it is plugged in or disconnected Electronic circuits of all types, especially modern digital equipment, are very sensitive to these types

of interference pulses The NSG 1025 Generator

ce sources dards are met and, particularly where precision and

reproducibility are concerned, are often exceeded new type of solid-state high voltage switch ensures excellent pulse parameter stability and maintenancefree continuous operation The instrument is equally suitable for laboratory and field tests as well as for routine testing for quality assurance purposes by a selection switch with fixed settings for the pulse parameters in conformity with the test classes contai-

permits the continuous setting of the test voltage and the free choice of the burst frequency for develop-

In addition the NSG 1025 can generate fast single pulses (5/50 ns transients) which are called for in various test Standards and which are also useful for detailed investigations in development laboratories

Internal and external trigger functions permit the

instrument to be flexibly adapted to the various needs A single-phase mains coupling network is incorporated in the unit which provides the coupling modes

called for in IEC 801-4 at the touch of a button besides

further coupling modes for special applications

The NSG 1025 is conveniently equipped with a

mains socket as well as universal safety sockets for connecting the test object The supply to the test object is separately switchable

Coupling clamps or coupling units for tests on data

lines or an auxiliary unit for three-phase coupling can

be connected via the HV coaxial connector

CDN 300 Fast Transient/Burst

Three Phase Coupling Network

for cost-effective compliance testing & characterization

The NSG 1025 fast transient/burst generator is a low cost, versatile instrument for compliance and pre-compliance

testing to IEC 1000-4-4, and for custom tests for design

characterization . Even though it offers more functionality and higher performance than other instruments in its class, the NSG 1025 is very competitively priced, helping test houses and in-house test facilities maximize the costeffectiveness of test resources

Testing to IEC 1000-4-4 could not be easier than with the NSG 1025 A simple selector switch on the front panel allows the user to choose the

appropriate voltage/frequency setting for levels 1 to 4 1000V/5kHz, 2000V/5kHz or 4000V/2

to test

For custom tests, front panel selector switches allow the user to manually set the voltage level to 4400V max, the frequency at 2

CDN 125 /126 Capacitive coupling clamps

The coupling clamps are primarily used

to inject interference pulses into signal and data cables, le into any type of connection to peripheral equipment

Both models have the same technical features, but the CDN 126 is also equipped with a safety interlock system (SIS)

CDN 300 1300-30

Fast transient I burst coupler

These couplers are used with burst

simulators and generators to inject IEC 1000-4-4 transients into equipment which requires three-phase power

The CDN 300 can handle up to 16A and the CDN 300-30 is a higher rated version for 30A
